Description
These high-voltage devices are Zener-protected N-channel Power MOSFETs
developed using the SuperMESH™ technology by STMicroelectronics, an
optimization of the well-established PowerMESH™. In addition to a significant
Product status reduction in on-resistance, these devices are designed to ensure a high level of dv/dt
capability for the most demanding applications.
